Would be useful for you to also include the condition of the disks.. maybe even similar to the "sleepy scale" used on dgcoursereview:

Disc Condition Scale aka "The Sleepy Scale"
10 - Never thrown, no ink, brand new condition
9 - Field tested or used for one or two rounds
8 - Lightly used with very minimal wear
7 - Used with some minor dings or scuffs but still in good shape
6 - Typical used disc with the usual dings, scratches but still worthy
5 - Kinda beat, significant wear, has lost a good bit of it's stability
4 - Beat up turnover disc with some evident war story wear
3 or under - Beat to Hades dog chew toy
